						</ul>
					</li>
				</ul>

				<p>Changes since version 1.3.6</p>
				<ul>
					<li>Overall, a small bugfix release.
					<li>New detection of accidental vacuous/useless calls to
						EasyMock methods, and of generic signatures that proclaim the use
						of unhashable classes in ways that require that they be hashed.
					<li>Eliminate some false positives where we were warning about
						a useless call (e.g., comparing two incompatible types for
						equality), but the only thing the code was doing with the result
						was passing it to assertFalse.
					<li>Japanese localization and manual by K.Hashimoto. (Thanks!)
					
					<li>Added -exclude and -outputDir command line options to
						rejarForAnalysis
					<li>Extended -adjustPriorities option to FindBugs analysis
						textui so that you can modify the priorities of individual bug
						patterns as well as visitors, and also completely suppress
						individual bug patterns or visitors.
						<ul>
							<li>e.g., -adjustPriority
								MS_SHOULD_BE_FINAL=suppress,MS_PKGPROTECT=suppress,EI_EXPOSE_REP=suppress,EI_EXPOSE_REP2=suppress,PZLA_PREFER_ZERO_LENGTH_ARRAYS=raise
							
						</ul>
				</ul>


				<p>Changes since version 1.3.5</p>
				<ul>
					<li>Added fairly exhaustive static analysis of uses of format
						strings, checking for missing or extra arguements, invalid format
						specifiers, or mismatched format specifiers and arguments (e.g,
						passing a String value for a %d format specifier). The logic for
						doing so is derived from Sun's java.util.Formatter class, and
						available separately from FindBugs as part of the <a
						href="https://jformatstring.dev.java.net/">jFormatString</a>
						project.
					<li>More tuning of the unsatisfied obligation detector. Since
						this detector is still rather noisy and an unfinished research
						project, I've moved the generated issues to a new category:
						EXPERIMENTAL.
					<li>Added check for <a
						href="http://findbugs.sourceforge.net/bugDescriptions.html#BIT_ADD_OF_SIGNED_BYTE">BIT_ADD_OF_SIGNED_BYTE</a>;
						similar to <a
						href="http://findbugs.sourceforge.net/bugDescriptions.html#BIT_IOR_OF_SIGNED_BYTE">BIT_IOR_OF_SIGNED_BYTE</a>,
						except that addition is being used to combine shifted signed
						bytes.
					<li>Changed detection of EI_EXPOSE_REP2, so we only report it
						if the value stored is guaranteed to be the same value that was
						passed in as a parameter.
					<li>Added <a
						href="http://findbugs.sourceforge.net/bugDescriptions.html#EQ_CHECK_FOR_OPERAND_NOT_COMPATIBLE_WITH_THIS">EQ_CHECK_FOR_OPERAND_NOT_COMPATIBLE_WITH_THIS</a>,
						a warning when an equals method checks to see if an operand is an
						instance of a class not compatible with itself. For example, if
						the Foo class checks to see if the argument is an instance of
						String. This is either a questionable design decision or a coding
						mistake.
					<li>Added <a
						href="http://findbugs.sourceforge.net/bugDescriptions.html#DMI_INVOKING_HASHCODE_ON_ARRAY">DMI_INVOKING_HASHCODE_ON_ARRAY</a>,
						which checks for invoking <code>hashCode()</code> on an array,
						which returns a hash code that ignores the contents of the array.
					
					<li>Added checks for using <code>x.removeAll(x)</code> to
						rather than <code>x.clear()</code> to clear an array.
					<li>Add checks for calls such as <code>x.contains(x)</code>, <code>x.remove(x)</code>
						and <code>x.containsAll(x)</code>.
					<li>Improvements to Eclipse plugin (thanks to Andrey
						Loskutov):
						<ul>
							<li>Report separate markers for each occurrence of an issue
								that appears multiple times in a method
							<li>fine tuning for reported markers: add only one marker
								for fields, add marker on right position
							<li>link bugs selected in bug explorer view to the opened
								editor and vice versa
							<li>select bugs selected in editor ruler in the opened bug
								explorer view
							<li>consistent abbreviations used in both bug explorer and
								bug details view
							<li>added "Expand All" button to the bug explorer view
							<li>added "Go Into/Go Up" buttons to the bug explorer view
							<li>added "Copy to clipboard" menu/functionality to the
								details view list widget
							<li>fix for CNF exception if loading the backup solution for
								broken browser widget
						</ul>
				</ul>



				<p>Changes since version 1.3.4</p>
				<ul>
					<li>Analysis about 15% faster
					<li><a
						href="http://sourceforge.net/tracker/?atid=614693&group_id=96405&func=browse&status=closed">38
							bugs closed</a></li>
					<li>New defect warnings:
						<ul>
							<li>calls to methods that always throw
								UnsupportedOperationException (DMI_UNSUPPORTED_METHOD)
							<li>repeated conditional tests (e.g., <code>if (x
									&lt; 0 || x &lt; 0) ...</code>) (RpC_REPEATED_CONDITIONAL_TEST)
							<li>Complete rewrite of detector for format string problems.
								More accurate, finds more problems, generates more descriptive
								reports, several different bug pattern
								(VA_FORMAT_STRING_EXTRA_ARGUMENTS_PASSED,
								VA_FORMAT_STRING_ILLEGAL, VA_FORMAT_STRING_MISSING_ARGUMENT,
								VA_FORMAT_STRING_BAD_ARGUMENT,
								VA_FORMAT_STRING_NO_PREVIOUS_ARGUMENT)
							<li>Fairly complete implementation of JSR-305 custom type
								qualifier analysis (no support for custom validators yet).
								(TQ_MAYBE_SOURCE_VALUE_REACHES_NEVER_SINK
								TQ_EXPLICIT_UNKNOWN_SOURCE_VALUE_REACHES_ALWAYS_SINK
								TQ_EXPLICIT_UNKNOWN_SOURCE_VALUE_REACHES_NEVER_SINK)
							<li>New detector for unsatisfied obligations such forgetting
								to close a file (OBL_UNSATISFIED_OBLIGATION).
							<li>Warning when a parameter is marked as nullable, but is
								always dereferenced.
								(NP_PARAMETER_MUST_BE_NONNULL_BUT_MARKED_AS_NULLABLE)
							<lI>Separate warning for dereference the result of readLine
								(NP_DEREFERENCE_OF_READLINE_VALUE)
						</ul>
					<li>When XML is generated with messages, the project stats now
						include &lt;FileStat&gt; elements. For each source file, this
						gives the path for the file, the total number of warnings for that
						file, and a bugHash for the file. While the instanceHash for a bug
						is intended to be version invariant (ignoring line numbers, etc),
						the bugHash for a file is intended to reflect all the information
						about the warnings in that file. The intended use case is that if
						the bugHash for a file is the same in two analysis runs, then <em>nothing</em>
						has changed about any of the warnings reported for that file
						between the two analysis runs.
					<li>More merging of similar issues within a method. For
						example, if the result of readLine() is dereferences multiple
						times within a method, it will be reported as a single warning
						with occurrences at multiple source lines.

				<p>Changes since version 1.3.0</p>
				<ul>
					<li>New Reports
						<ul>
							<li>VA_FORMAT_STRING_ARG_MISMATCH: A format-string method
								with a variable number of arguments is called, but the number of
								arguments passed does not match with the number of %
								placeholders in the format string. This is probably not what the
								author intended.
							<li>IO_APPENDING_TO_OBJECT_OUTPUT_STREAM: This code opens a
								file in append mode and that wraps the result in an object
								output stream. This won't allow you to append to an existing
								object output stream stored in a file. If you want to be able to
								append to an object output stream, you need to keep the object
								output stream open. The only situation in which opening a file
								in append mode and the writing an object output stream could
								work is if on reading the file you plan to open it in random
								access mode and seek to the byte offset where the append
								started.
							<li>NP_BOOLEAN_RETURN_NULL: A method that returns either
								Boolean.TRUE, Boolean.FALSE or null is an accident waiting to
								happen. This method can be invoked as though it returned a value
								of type boolean, and the compiler will insert automatic unboxing
								of the Boolean value. If a null value is returned, this will
								result in a NullPointerException.

							<li>SynchronizationOnSharedBuiltinConstant
								<ul>
									<li>DL_SYNCHRONIZATION_ON_SHARED_CONSTANT: The code
										synchronizes on a shared primitive constant, such as an
										interned String. Such constants are interned and shared across
										all other classes loaded by the JVM. Thus, this could be
										locking on something that other code might also be locking.
										This could result in very strange and hard to diagnose
										blocking and deadlock behavior. See <a

								<ul>
									<li>TQ_ALWAYS_VALUE_USED_WHERE_NEVER_REQUIRED: A value

									<li>EQ_DOESNT_OVERRIDE_EQUALS: This class extends a class
										that defines an equals method and adds fields, but doesn't
										define an equals method itself. Thus, equality on instances of
										this class will ignore the identity of the subclass and the
										added fields. Be sure this is what is intended, and that you
										don't need to override the equals method. Even if you don't
										need to override the equals method, consider overriding it

									<li>NM_SAME_SIMPLE_NAME_AS_SUPERCLASS: This class has a
										simple name that is identical to that of its superclass,
										except that its superclass is in a different package (e.g., <code>alpha.Foo</code>
										extends <code>beta.Foo</code>). This can be exceptionally
										confusing, create lots of situations in which you have to look
										at import statements to resolve references and creates many
										opportunities to accidently define methods that do not
										override methods in their superclasses.
									</li>
									<li>NM_SAME_SIMPLE_NAME_AS_INTERFACE: This class/interface
										has a simple name that is identical to that of an
										implemented/extended interface, except that the interface is
										in a different package (e.g., <code>alpha.Foo</code> extends <code>beta.Foo</code>).
										This can be exceptionally confusing, create lots of situations

									</li>
								</ul>
							<li>FindRefComparison
								<ul>
									<li>EC_UNRELATED_TYPES_USING_POINTER_EQUALITY: This method

									<li>BIT_SIGNED_CHECK, BIT_SIGNED_CHECK_HIGH_BIT: This
										method compares an expression such as <tt>((event.detail
											&amp; SWT.SELECTED) &gt; 0)</tt>. Using bit arithmetic and then
										comparing with the greater than operator can lead to
										unexpected results (of course depending on the value of
										SWT.SELECTED). If SWT.SELECTED is a negative number, this is a
										candidate for a bug. Even when SWT.SELECTED is not negative,
										it seems good practice to use '!= 0' instead of '&gt; 0'.
									</li>
								</ul>
							</li>
							<li>LazyInit
								<ul>
									<li>LI_LAZY_INIT_UPDATE_STATIC: This method contains an
										unsynchronized lazy initialization of a static field. After
										the field is set, the object stored into that location is
										further accessed. The setting of the field is visible to other
										threads as soon as it is set. If the further accesses in the
										method that set the field serve to initialize the object, then
										you have a <em>very serious</em> multithreading bug, unless
										something else prevents any other thread from accessing the
										stored object until it is fully initialized.
									</li>
								</ul>
							</li>
							<li>FindDeadLocalStores
								<ul>
									<li>DLS_DEAD_STORE_OF_CLASS_LITERAL: This instruction
										assigns a class literal to a variable and then never uses it.
										<a href="//java.sun.com/j2se/1.5.0/compatibility.html#literal">The
											behavior of this differs in Java 1.4 and in Java 5.</a> In Java
										1.4 and earlier, a reference to <code>Foo.class</code> would
										force the static initializer for <code>Foo</code> to be
										executed, if it has not been executed already. In Java 5 and
										later, it does not. See Sun's <a
										href="//java.sun.com/j2se/1.5.0/compatibility.html#literal">article
											on Java SE compatibility</a> for more details and examples, and
										suggestions on how to force class initialization in Java 5.
									</li>
								</ul>
							</li>
							<li>MethodReturnCheck
								<ul>
									<li>RV_RETURN_VALUE_IGNORED_BAD_PRACTICE: This method
										returns a value that is not checked. The return value should
										be checked since it can indication an unusual or unexpected
										function execution. For example, the <code>File.delete()</code>
										method returns false if the file could not be successfully
										deleted (rather than throwing an Exception). If you don't
										check the result, you won't notice if the method invocation
										signals unexpected behavior by returning an atypical return
										value.
									</li>
									<li>RV_EXCEPTION_NOT_THROWN: This code creates an
										exception (or error) object, but doesn't do anything with it.

						</ul>
					<li>Enabled StaticCalendarDetector</li>
					<li>Reworked GUI2 to use standard FindBugs filters
						<ul>
							<li>Allow a suppression filter to be stored in a project and
								persisted to the XML representation of a project.</li>
						</ul>
					</li>

					<li>Move away from old GUI2 save format (a directory
						containing an xml file and another file containing serialized
						filters).</li>
					<li>Support/recommend use of two new file extensions/formats:
						<dl>
							<dt>.fba - FindBugs Analysis File</dt>
							<dd>Exactly the same as an existing bug collection file
								stored in XML format, but using a distinct file extension to
								make it easier to figure out which xml files contain FindBugs
								results.</dd>
							<dt>.fbp - FindBugs Project File</dt>
							<dd>Contains just the information needed to run FindBugs and
								display the results (e.g., the files to be analyzed, the
								auxiliary class path and the location of source files)
						</dl>
					</li>
				</ul>
				<p>Changes since version 1.1.3</p>
				<ul>
					<li>Added -xml:withAbridgedMessages option to generate xml
						containing shorter messages. The messages will be shorted by doing
						things like eliding package names, and leaving off the source line
						from the LongMessage. These messages are appropriate if being used
						in a context where the non-message components of the bug
						annotations will be used to provide more information (e.g.,
						clicking on the message for a MethodAnnotation will display the
						source for the method).
						<ul>
							<li>FindBugsDisplayFeatures.setAbridgedMessages(true) can be
								used to generate abridged messages when FindBugs is being
								accessed directly (not via generated XML) from a GUI or IDE.</li>
						</ul>
					<li>In null pointer analysis, try to be better about always
						showing two locations: where it is known null and where it is
						dereferenced.
					<li>Interprocedural analysis of which methods return nonnull
						values
					<li>Use method calls to select order in which classes are
						analyzed, and order in which methods are analyzed, to improve
						interprocedural analysis results.
					<li>Significant improvements in memory footprint, memory
						allocation and CPU utilization (20-30% reduction in all three)
					<li>Added a project name, to provide better descriptions in
						the HTML output.
					<li>Added new bug pattern: Casting to char, or bit masking
						with nonnegative value, and then checking to see if the result is
						negative.
					<li>Stopped reporting transient fields of classes not marked
						as serializable. Transient is used by other persistence
						frameworks.
					<li>Improvements to detector for SQL injection (Thanks to <a
						href="http://www.clock.org/~matt">Matt Hargett</a> for his
						contributions
					<li>Changed open/save options in GUI2 to not distinguish
						between FindBugs projects and saved FindBugs analysis results.

				</ul>
				<p>Changes since version 1.1.1:</p>
				<ul>
					<li>Added check for infinite iterative loops</li>
					<li>Added check for use of incompatible types in a collection
						(e.g., checking to see if a Set&lt;String&gt; contains a
						StringBuffer).</li>
					<li>Added check for invocations of equals or hashCode on a
						URL, which, <a
						href="http://michaelscharf.blogspot.com/2006/11/javaneturlequals-and-hashcode-make.html">surprising
							many people</a>, requires DNS resolution.
					</li>
					<li>Added check for classes that define compareTo but not
						equals; such classes can exhibit some anomalous behavior (e.g.,
						they are treated differently by PriorityQueues in Java 5 and Java
						6).</li>
					<li>Added a check for useless self operations (e.g., x &lt; x
						or x ^ x).</li>
					<li>Fixed a data race that could cause the GUI to fail on
						startup</li>
					<li>Partial internationalization of the new GUI</li>
					<li>Fix bug in "Redo analysis" option of new GUI</li>
					<li>Tuning to reduce false positives</li>

						exceptions on exception paths.</li>
					<li>Fixed a bug in the processing of phi nodes for fields in
						the null pointer analysis</li>
					<li>Applied contributed patch that provides more quick fixes
						in Eclipse plugin.</li>
					<li>Fixed a number of bugs in the Eclipse auto update sites,
						and in the way date qualifiers were being used in the Eclipse
						plugin. You may need to manually disable your existing version of
						the plugin and download the 1.1.2 from the update site to get the
						automatic update function working correctly. The Eclipse update
						sites are described at <a
						href="http://findbugs.cs.umd.edu/eclipse/">http://findbugs.cs.umd.edu/eclipse/</a>.

					<li>Eclipse plugin
						<ul>
							<li>bug annotation info displayed in Bug Details tab</li>

						</ul>
					</li>
					<li>new SE_BAD_FIELD_INNER_CLASS pattern</li>
					<li>updates to Japanese translation (ruimo)</li>
					<li>fix some internal slashed/dotted path confusion</li>
					<li>other minor improvements</li>
				</ul>

				<p>Changes since version 1.0.0:</p>

				<ul>
					<li>Overall, the change from FindBugs 1.0.0 to FindBugs 1.1.0
						has been a big change. We've done a lot of work in a lot of areas,
						and aren't even going to try to enumerate all the changes.</li>
					<li>We spent a lot of time reviewing the results generated by
						FindBugs for open source and commercial code bases, and made a
						number of changes, small and large, to minimize the number of
						false positives. Our primary focus for this was warnings reported
						as high and medium priority correctness warnings. Our internal
						evaluation is that we produce very few high/medium priority
						correctness warnings where the analysis is actually wrong, and
						that more than 75% of the high/medium priority correctness
						warnings correspond to real coding defects that need addressing in
						the source code. The remaining 25% are largely cases such as a
						branch or statement that if taken would lead to an error, but in
						fact is a dead branch or statement that can never be taken. Such
						coding is confusing and hard to maintain, so it should arguably be
						fixed, but it is unlikely to actually result in an error during
						execution. Thus, some might classify those warnings as false
						positives.</li>
					<li>We've substantially improved the analysis for errors that
						could result in null pointer dereferences. Overall, our experience
						has been that these changes have roughly doubled the number of
						null pointer errors we detect, without increasing the number of
						false positives (in fact, our false positive rate has gone down).
						The improvements are due to four factors:
						<ul>
							<li>By default, we now do some interprocedural analysis to
								determine methods that unconditionally dereference their
								parameters.</li>
							<li>FindBugs also comes with a model of which JDK methods
								unconditionally dereference their parameters.</li>
							<li>We do limited tracking of fields, so that we can detect
								null values stored in fields that lead to exceptions.</li>
							<li>We implemented a new analysis technique to find
								guaranteed dereferences. Consider the following example: <pre>public int f(Object x, boolean b) {
  int result = 0;
  if (x == null) result++;
  else result--;
  // at this point, we know x is null on a simple path
  if (b) {
    // at this point, x is only null on a complex path
    // we don't know if the path in which x is null and b is true is feasible
    return result + x.hashCode();
    }
  else {
    // at this point, x is only null on a complex path
    // we don't know if the path in which x is null and b is false is feasible
    return result - x.hashCode();
    }
</pre>

								<p>
									FindBugs 1.0 used forward dataflow analysis to determine
									whether each value is definitely null, null on a simple path,
									possible null on a complex path, or definitely nonnull. Thus,
									at the statement where
									<code> result </code>
									is decremented, we know that
									<code> x </code>
									is definitely null, and at the point before
									<code> if (b) </code>
									, we know that
									<code> x </code>
									is null on a simple path. If
									<code> x </code>
									were to be dereferenced here, we would generate a warning,
									because if the else branch of the
									<code> if (x == null) </code>
									were ever taken, a null pointer exception would result.
								</p>

								<p>
									However, in both the then and else branches of the
									<code> if (b) </code>
									statement,
									<code> x </code>
									is only null on a complex path that may be infeasible. It might
									be that the program logic is such that if
									<code> x </code>
									is null, then
									<code> b </code>
									is never true, so generating a warning about the dereference in
									the then clause might be a false positive. We could try to
									analyze the program to determine whether it is possible for
									<code> x </code>
									to be null and
									<code> b </code>
									to be true, but that can be a hard analysis problem.
								</p>

								<p>
									However,
									<code> x </code>
									is dereferenced in both the then <em>and</em> else branches of
									the
									<code> if (b) </code>
									statement. So at the point immediately before
									<code> if (b) </code>
									, we know that
									<code> x </code>
									is null on a simple path <em>and</em> that
									<code> x </code>
									is guaranteed to be dereferenced on all paths from this point
									forward. FindBugs 1.1 performs a backwards data flow analysis
									to determine the values that are guaranteed to be dereferenced,
									and will generate a warning in this case.
								</p>
							</li>
						</ul>
						<p>
							The following screen shot of our new GUI shows an example of this
							analysis, as well as showing off our new GUI and points out a
							limitation of our current plugins for Eclipse and NetBeans. The
							screen shot shows a null pointer bug in HelpDisplay.java. The
							test for
							<code> href!=null </code>
							on line 78 suggests that
							<code> href </code>
							could be null. If it is, then
							<code> href </code>
							will be dereferenced on either line 87 or on line 90, generating
							a NPE. Note that our analysis here also understands that passing
							<code> href </code>
							to
							<code> URLEncoder.encode </code>
							will deference it, and thus treats line 87 as a dereference, even
							though
							<code> href </code>
							is not actually dereferenced at that line. Within our new GUI,
							all of these locations are highlighted and listed in the summary
							panel. In the original GUI (and in HTML output) we list all of
							the locations, but only the primary location is highlighted by
							the original GUI. In the Eclipse and NetBeans plugins, only the
							primary location is displayed; fixing this is on our todo list
							(contributions welcome).

					</li>
					<li>Preliminary support for detectors using the frameworks
						other than BCEL, such as the <a href="http://asm.objectweb.org/">ASM</a>
						bytecode framework. You may experiment with writing ASM-based
						detectors, but beware the API may still change (which could
						possibly also affect BCEL-based detectors). In general, we've
						started trying to move away from a deep dependence on BCEL, but
						that change is only partially complete. Probably best to just
						avoid this until we complete more work on this. This change is
						only visible to FindBugs plugin developers, and shouldn't be
						visible to FindBugs users.
					</li>
					<li>
						<p>Bug categories (CORRECTNESS, MT_CORRECTNESS, etc.) are no
							longer hard-coded, but rather defined in xml files associated
							with plugins, including the core plugin which defines the
							standard categories. Third-party plugins can define their own
							categories.</p>
					</li>
					<li>
						<p>Several bug patterns have been moved from CORRECTNESS and
							STYLE into a new category, BAD_PRACTICE. The English localization
							of STYLE has changed from "Style" to "Dodgy."</p>
						<p>In general, we've worked very hard to limit CORRECTNESS
							bugs to be real programming errors and sins of commission. We
							have reclassified as BAD_PRACTICE a number of bad design
							practices that result in overly fragile code, such as defining an
							equals method that doesn't accept null or defining class with a
							equals method that inherits hashCode from class Object.</p>
						<p>In general, our guidelines for deciding whether a bug
							should be classified as CORRECTNESS, BAD_PRACTICE or STYLE are:</p>
						<dl>
							<dt>CORRECTNESS</dt>
							<dd>A problem that we can recognize with high confidence and
								is an issue that we believe almost all developers would want to
								examine and address. We recommend that software teams review all
								high and medium priority warnings in their entire code base.</dd>
							<dt>BAD_PRACTICE</dt>
							<dd>A problem that we can recognize with high confidence and
								represents a clear violation of recommended and standard coding
								practice. We believe each software team should decide which bad
								practices identified by FindBugs it wants to prohibit in the
								team's coding standard, and take action to remedy violations of
								those coding standards.</dd>
							<dt>STYLE</dt>
							<dd>These are places where something strange or dodgy is
								going on, such as a dead store to a local variable. Typically,
								less than half of these represent actionable programming
								defects. Reviewing these warnings in any code under active
								development is probably a good idea, but reviewing all such
								warnings in your entire code base might be appropriate only in
								some situations. Individual or team programming styles can
								substantially influence the effectiveness of each of these
								warnings (e.g., you might have a coding practice or style in
								your group that confuses one of the detectors into generating a
								lot of STYLE warnings); you will likely want to selectively
								suppress or report the STYLE warnings that are effective for
								your group.</dd>
						</dl>
					</li>
					<li>Released a preliminary version of a new GUI (known
						internally as GUI2 -- not very creative, huh?)</li>
					<li>Provided standard ways to mark user designations of bug
						warnings (e.g., as NOT_A_BUG or SHOULD_FIX). The internal logic
						now records this, it is represented in the XML file, and GUI2
						allows the designations to be applied (along with free-form user
						annotations about each warning). The user designations and
						annotations are not yet supported by the Eclipse plugin, but we
						clearly want to support it in Eclipse shortly.</li>
					<li>Added a check for a bad comparison with a signed byte with
						a value not in the range -128..127. For example: <pre>boolean find200(byte b[]) {
  for(int i = 0; i &lt; b.length; i++) if (b[i] == 200) return i;
  return -1;
}
</pre>
					</li>
					<li>Added a checking for testing if a value is equal to
						Double.NaN (no value is equal to NaN, not even NaN).</li>
					<li>Added a check for using a class with an equals method but
						no hashCode method in a hashed data structure.</li>
					<li>Added check for uncallable method of an anonymous inner
						class. For example, in the following code, it is impossible to
						invoke the initalValue method (because the name is misspelled and
						as a result is doesn't override a method in ThreadLocal). <pre>private static ThreadLocal serialNum = new ThreadLocal() {
         protected synchronized Object initalValue() {
             return new Integer(nextSerialNum++);
         }
     };
</pre>
					</li>
					<li>Added check for a dead local store caused by a switch
						statement fall through</li>
					<li>Added check for computing the absolute value of a random
						32 bit integer or of a hashcode. This is broken because <code>
							Math.abs(Integer.MIN_VALUE) == Integer.MIN_VALUE </code> , and thus
						result of calling Math.abs, which is expected to be nonnegative,
						will in fact be negative one time out of 2 <sup> 32 </sup> , which
						will invariably be the time your boss is demoing the software to
						your customers.

					</li>
					<li>More careful resolution of inherited methods and fields.
						Some of the shortcuts we were taking in FindBugs 1.0.0 were
						leading to inaccurate results, and it was fairly easy to address
						this by making the analysis more accurate.</li>
					<li>Overall, analysis times are about 1.6 times longer in
						FindBugs 1.1.0 than in FindBugs 1.0.0. This is because we have
						enabled substantial additional analysis at the default effort
						level (the actual analysis engine is significantly faster than in
						FindBugs 1.0). On a recent AMD Athlon processor, analyzing
						JDK1.6.0 (about 1 million lines of code) requires about 15 minutes
						of wall clock time.</li>
					<li>Provided class and script (printClass) to print classfile
						in the human readable format produced by BCEL</li>
					<li>Provided -findSource option to setBugDatabaseInfo</li>

						FindBugs, contributed by Mike Fagan.
					</li>

						not found errors are more informative.</li>
					<li>Minor GUI improvements.</li>
				</ul>

				<p>Changes since version 0.5.2</p>
				<ul>
					<li>All of the source code and related files are in a single
						directory tree.</li>
					<li>Updated some of the detectors to produce source line
						information.</li>
					<li><a href="http://ant.apache.org/">Ant</a> build script and

							architecture</a> for loading bug detectors.
					</li>
					<li>Eliminated generics-related compiler warnings.</li>
					<li>More complete documentation has been added.</li>
				</ul>

				<p>Changes since version 0.5.1:</p>
				<ul>
					<li>Fixed a large number of bugs in the BCEL Repository and
						FindBugs's use of the Repository.&nbsp; With these changes,
						FindBugs should <em>never</em> crash or otherwise misbehave
						because of Repository lookup failures.&nbsp; Because of these
						changes, you must use a modified version of <code> bcel.jar
						</code> with FindBugs.&nbsp; This jar file is included in the FindBugs
						0.5.2 binary release.&nbsp; A complete patch containing the <a
						href="http://faculty.ycp.edu/~dhovemey/bcel-30-April-2003.patch">modifications
							against the BCEL CVS main branch as of April 30, 2003</a> is also
						available.
					</li>
					<li>Implemented the "auxiliary classpath entry list".&nbsp;
						Aux classpath entries can be added to a project to provide classes
						that are referenced by the analyzed application, but should not
						themselves be analyzed.&nbsp; Having all referenced classes
						available allows FindBugs to produce more accurate results.</li>
				</ul>

				<p>Changes since version 0.5.0:</p>
				<ul>
					<li>Many user interface bugs have been fixed.</li>
					<li>Upgraded to a recent CVS version of BCEL, with some bug
						fixes.&nbsp; This should prevent FindBugs from crashing when there
						is a failure to find a class on the classpath.</li>
					<li>Added support for Plastic look and feel from <a
						href="http://www.jgoodies.com/">jgoodies.com</a>.
					</li>
					<li>Major overhaul of infrastructure for doing dataflow
						analysis.</li>
